SPECIFICATION formingpart of Letters Patent No. 280,423, dated July 3, 1883,

' Application iilod March 10, 1883. (No model.)

To all whom it may concern,-

Be it known that we, SIMON PETER WVEL- LER and GEORGE E. RoEscn, citizens of the United States, residing at Denver, in the 5 county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Lubricating-ups, of which the following is a specification, reference being had therein to the accompanying drawings.

[0 Our invention relates to lubricating-cups to be used for grease, tallo'w, or any other lubricating substance that has a greater density than oil used in lubricating; and it consists in the parts which will be hereinafter de I scribed, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a central vertical section of our improvement. Fig. 2 is an outside elevation. Fig. 3 is a side view of the spindle. Fig. 4: is a crosssection on the line w w of Fig. 1. Fig. 5 shows a plan and elevation of the piston and packing, and Fig. 6 a plan and elevation of the thumb-piece which surmounts the cup.

Like letters indicate like parts throughout the views.

The cup A, piston B, and spindle O constitute the chief part of the cup. The spindle C revolves in the cap E, which is screwed fast to the cup A. The thumb-piece F is fastenedto o spindle O by means of a small pin, Q. lVhen it is turnedit causes the piston to move down ward along thespindle O. The spindle is fitted with a thread to piston B. The piston is packed with an elastic substance, P, so that 3 5 the tallow or lubricating substance cannot pass to the upper part of the cup. The lower extremity of spindle C may be triangular, flat, or oval in cross-section, and loosely fitted and passed out through the bottom of cup, the spindle being at a convenient distance from revolving shaft. The lubricating substance can escape and pass out to revolving shaft through this opening as the shaft becomes heated by friction. The conductive power of the spindle C will melt and cause the fallow or lubricating substance to flow.

D is a collar on the spindle O.

O is a groove in the top of said spindle.

The pin Q fits into the grooves F and 0, whereby the thumb-screw F is secured to the spindle.

H is the lower end of the spindle.

G is a spring secured in the cup and eX- tending inwardly to one of the flat sides of the collar D, whereby the spindle is prevented from turning.

Having thus described our invention, we claim as new'and desire to secure by Letters Patent The cup A, cap E, and thumb-piece F, in combination with the spindle O, collar D, follower B, and spring G, substantially as described, and for the purposes set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
